    Thanks for this Marvin. I'm sure you are right about it being a binomial distibution formula but I too am unsure of how to use the binomial function in this situation.

    I understand what has been done here by using the random formula against each act and I guess this would work well. It is also an interesting to simulate the number of yes votes.

    Can I just check the VBA code is correct though? I have had a look at the code and although I can't say I completely understand it, I have managed to change the number of loops to just one rather than 1,000 to test it and it doesn't seem to work how I understand it should.

    The way I understand it is when you press the button the worksheet does a calculate and 1 is added to the count in the table B10:C17 corresponding to the count in cell G8.

    Marvin's Monte Carlo approach is great.

    For cases this small, you can enumerate the probabilities as attached. The numbers agree well with Marvin's, and his would be even closer if you increased the number of trial.

    There may well be a way to solve this in closed form, but I don't know the method.
